Hi everyone, I hope I post this question in the right section. On my webhost mochahost i'm trying to login to my cpanel and redirect to the roundcube webmail. Because I made a customized login form on my website for the webmail and I want to use that rather than the cpanel style. I don't have much experience with cURL, but after some tries I got a 200 header. Now I got the page after login, which is good, but with this host I have to chose between 3 mailapps (squirrel, horde and roundcube). And this is where I got stuck. I can't find out how to redirect to roundcube without losing the authentication. Here is my code: Code: $post = array(); $post['user'] = 'myusername'; $post['pass'] = 'mypassword'; $post['goto_uri'] = '/'; $post['login_theme'] = 'cpanel'; $url = 'https://eleanor.mochahost.com:2096/login/'; $ch = curl_init(); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt'); curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); // grab URL and pass it to the browser $response = curl_exec($ch); echo $response; // close cURL resource, and free up system resources curl_close($ch); I want to get in to roundcube so I looked into the link with firebug and I tried to change the Code: $post['goto_uri'] = '/'; to Code: $post['goto_uri'] = '/3rdparty/roundcube/index.php'; which I tought should do the trick, but unfortunately it wasn't that easy. Now i got an error: I also tried the sample php authentication script from the "Authenticating API Function Calls "-page. But also no luck there. Hope somebody can help me out, thanks in advance!
